Benefits of technology

[0178]The hair treated with the anhydrous formula of the disclosed composition had significantly less transfer of oil than the hair treated with an anhydrous formula of traditional soap. The lower transfer of oil from the hair results in improved hair color retention.4. Color Retention Study of The Disclosed Composition with a Pigment Objective:
[0194]Overall the results from experiments 1-8 illustrated the ability of the disclosed composition to unexpectedly inhibit color fading in hair. Specifically the disclosed composition unexpectedly improves hair properties such as water-resistance, non-transfer of pigment, non-transfer of oil, and hair color retention. These properties lead to improved hair color retention in both dyed and naturally colored hair.

Problems solved by technology

Both naturally and artificially colored (dyed) hair can lose its color over time.
The loss in color is a result of fading due to environmental conditions such as high and low humidity and sunlight.
For dyed hair, color can be lost from handling, everyday activities and washing.
In addition, the barrier should not be easily transferred from the hair over time through normal activities.

Embodiment Construction

[0004]The term “comprising” (and its grammatical variations) as used herein is used in the inclusive sense of “having” or “including” and not in the exclusive sense of “consisting only of”. The terms “a” and “the” as used herein are understood to encompass the plural as well as the singular.

[0005]Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions are to be understood as being modified in all instances by the term “about”.

[0006]The term “water-insoluble” means those compounds which are either completely or partially insoluble in water.

[0007]“At least one” as used herein means one or more and thus includes individual components as well as mixtures / combinations.

[0008]“Substituted,” as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether gr...

Abstract

The disclosure relates to compositions and methods of using the compositions to inhibit color fading in hair. The compositions provide a water resistant and non-transferable protective barrier on the substrate that inhibits color fading in both dye and naturally colored hair. The compositions contain at least one polyamine, at least one acid, at least one water-insoluble ingredient, solvent and optionally at least one auxiliary ingredient. The methods for inhibiting color fading in hair involve contacting the hair with the compositions of the disclosure.

Description

TECHNICAL FIELD[0001]The disclosure relates to compositions and methods for inhibiting color fading in hair. The compositions and methods provide a water resistant and non-transferable protective barrier on hair that inhibits color fading in both dyed and naturally colored hair.BACKGROUND OF THE DISCLOSURE[0002]The disclosure relates to compositions and methods for inhibiting color fading in hair. Both naturally and artificially colored (dyed) hair can lose its color over time. The loss in color is a result of fading due to environmental conditions such as high and low humidity and sunlight. For dyed hair, color can be lost from handling, everyday activities and washing. A barrier applied to the hair would be useful in protecting the hair from fading. Such a barrier would be useful in minimizing dye loss from dyed hair. Such a barrier should be water-resistant so that the hair maintains the protective barrier under everyday conditions such as washing. In addition, the barrier should...
